Description

New S9 series three phased oil-immersed transformer adopts such scientific achivements as new structures of insulation and anti-short circuit etc. Its perforance has reached international advanced level. Compared to S7 series, the No-load loss decreases by *0.*5% in average, no-load current *7.9%, load loss *2.4% in average, it is the upgraded version for energy saving. Transforme Main functions and characters 1. Low loss, energy saving visible; 2. Iron core is in round form, multi-stage, and entire tilted three stages seaming and lapping structure; 3. High and low voltage windings are wrapped with deoxidized copper. All high voltage windings are with multilayer drum type. 4. Reasonable layout 5. New parts and fasteners
